    Is it possible to bind to the Metro Theme AccentColor in code behind?

    I found it easy to do in XAML:
    <SolidColorBrush x:Key="AccentBrush" Color="{Binding Source={StaticResource MetroColors}, Path=Palette.AccentColor}" />

    Setting the color using radGrid.BorderBrush = new SolidColorBrush(MetroColors.PaletteInstance.AccentColor); does not update the radGrid's BorderBrush when the AccentColor is changed.
    In code behind I'm get the exception "Cannot find a Resource with the Name/Key MetroColors [Line: 10 Position: 36]" when I try to use the following binding:
                Binding accentColor = new Binding("Palette.AccentColor");
                accentColor.Source = App.Current.Resources["MetroColors"];
                accentColor.Converter = new ColorToBrushConverter();
                radGrid.SetBinding(RadGridView.BorderBrushProperty, accentColor);

    Hello Shawn,

     It's not necessary to bind to the Metro Theme in code behind. Actually, if you want to change some properties of a specific control, based on Metro Theme, you can define a style based on the theme and change the colors in it. Check the following code snippet for reference:

      <Style x:Key="s1" TargetType="telerik:RadGridView" telerik:StyleManager.BasedOn="Metro">
        <Setter Property="BorderBrush" Value="Orange"/>
      <Grid x:Name="LayoutRoot" Background="White" DataContext="{Binding Source={StaticResource SampleDataSource}}">
        <telerik:RadGridView telerik:StyleManager.Theme="Metro" Style="{StaticResource s1}" ItemsSource="{Binding Collection}"/>

    Kind regards,

    Hi Yoan,

    Thank you for the reply. I think this answers my question, what you're saying is it's not possible to do this in the code-behind.

    Also, thank you for the XAML example.
